1 Claim. (Cl. 15--121) This invention relates to a window washingsponge. The invention is more particularly applicable for use in fillingstations and the like for washing the windows and Windshields ofautomobiles.

It is usually necessary to wash the windows and wind- I shields with asponge, after which the surfaces are dried by means of a chamois skin orother drying medium. The principal object of this invention is tocombine with an absorbent washing sponge, a relatively straight,flexible edge or corner whereby the sponge may be used for the usualwashing purposes and the corner or edge may be used as a water removingsqueegee.

Another object of the invention is to combine the squeegee as anintegral part of the sponge where it will serve as a resilientstiffening member, hand grip, and reinforcement for the cellular spongeportion.

Other objects and advantages reside in the detail construction of theinvention, which is designed for simplicity, economy, and efiiciency.These will become more apparent from the following description.

In the following detailed description of the invention, reference is hadto the accompanying drawing which forms a part hereof. Like numeralsrefer to like parts in all views of the drawing and throughout thedescription.

In the drawing:

Fig. 1 is a perspective view of the improved combination squeegee andsponge;

Fig. 2 is a cross-section therethrough, taken on the line 22, Fig. 1;

Fig. 3 is a perspective view illustrating a slightly alternate form ofthe improved squeegee and sponge; and

Fig. 4 is a magnified fragmentary corner section of another form of theimproved sponge.

The first form of the invention consists of a relatively flat,rectangular block or sponge formed from foam rubber, cellular Neoprene,or similar synthetic sponge material.

One of the longitudinal corner edges of the sponge 10 is provided with arelatively straight, sharp, flexible corner edge member 11. The corneredge member is triangular in cross-section and may be applied to thesponge 10 in several ways. For instance, it could be molded as a solidportion at the time of molding the sponge to form an integral unittherewith. It could be a separate triangular strip of rubber or similarflexible material cemented or otherwise secured along one corner edge ofthe sponge 10.

Another method of applying the straight squeegee edge to the sponge inan economical, rapid, and facile man- 2,715,745 Patented Aug. 23, 1955 2ner is illustrated in Fig. 4 in which the open cells of the sponge areindicated at 15. In this method, one longitudinal corner edge of thesponge 10 is dipped in liquid rubber or latex cement solution, allowingthe solution to penetrate into the cells 15 along the corner of thesponge, as indicated at 16 in Fig. 4, so that the dipped corner willpresent a solid, flexible, resilient structure, whereas the remainder ofthe sponge will have an open, absorbent, cellular construction. Theentrapped compound, indicated at 16, may be cured either by air exposureor heat to form a resilient solid mass.

In use, the window or windshield is sponged oif by using any desiredsurfaces of the sponge 10. The drying is accomplished by placing thecorner edge member 11 against the glass surface and drawing it across,similar to the usual window dryers squeegee.

In Fig. 3 an alternate form of the invention is illustrated, comprisinga cellular, absorbent sponge 12, to two longitudinal corner edges of oneface of which flexible strips 13 are applied. The strips 13 are formedwith outwardly extending, flexible bead portions 14 which serve asdrying squeegees similarly to the portion 11 of the previous form.

The two strips 13, with their beads 14, form, in addi tion to squeegees,hand grips for the sponge 12, and also serve as stiffening members forresisting bending of the sponge. It has also been found that if the twocorner portions 13 of the sponge 12 are gripped in the hand, it willtend to bow the middle of the front of the sponge outwardly to form asoft, rounded, and efficient washing surface. The strips 13 may beapplied to the sponge 12 in any of the manners described above withrelation to the strip 11.

While a specific form of the improvement has been described andillustrated herein, it is to be understood that the same may be varied,within the scope of the appended claim, without departing from thespirit of the invention.

Having thus described the invention, What is claimed and desired securedby Letters Patent is:

A window washing sponge and squeegee comprising: a substantiallyrectangular sponge block of cellular, resilient material; a squeegeecorner edge member of noncellular resilient material extending along andforming one corner edge of said block for the full length thereof, thecross section of said squeegee corner edge member forming substantiallya right triangle with its hypotenuse joined to said sponge block andwith its sides in the planes of the two adjacent sides of said block.
